Thupi la valve limagwiritsa ntchito zinthu za GGG50, zimakhala ndi makina apamwamba kwambiri, mlingo wa spheroidization kuposa kalasi ya 4, umapangitsa kuti ductility ya zinthuzo ikhale yoposa 10 peresenti.Poyerekeza ndi chitsulo choponyedwa nthawi zonse, imatha kuvutitsidwa kwambiri.

Mpando wa valve wokhala ndi 3 bushing ndi 3 O mphete, umathandizira kuthandizira tsinde ndikutsimikizira kusindikiza.

Vavu iliyonse iyenera kutsukidwa ndi makina oyeretsera a ultra-sonic, ngati zoipitsidwa zitatsala mkati, zitsimikizireni kuyeretsedwa kwa valavu, ngati kuipitsidwa kwa payipi.

Maboti ndi mtedza zimagwiritsa ntchito zinthu za SS304, zokhala ndi mphamvu zoteteza dzimbiri.

Chogwirizira cha valve chimagwiritsa ntchito chitsulo cha ductile, ndi anti-corrosion kuposa chogwirira chanthawi zonse.Spring ndi pini zimagwiritsa ntchito zinthu za SS304.Gwiritsani ntchito mawonekedwe a semicircle, ndikumverera kwabwino.

Mapangidwe a tsinde opanda pini amatengera mawonekedwe odana ndi kuphulika, tsinde la valavu limatenga mphete yodumphira pawiri, osati kungobwezera cholakwikacho pakuyika, komanso kuletsa tsinde kuphulika.

Chilichonse cha ZFA chili ndi lipoti lazinthu zamagulu akulu a valve.

Thupi la ZFA Valve limagwiritsa ntchito thupi lolimba la valve, kotero kulemera kwake ndikwambiri kuposa mtundu wamba.

Ma actuators a pneumatic amatengera mawonekedwe a pistoni awiri, olondola kwambiri komanso ogwira mtima, komanso torque yokhazikika.

Mayeso a Thupi: Kuyeza kwa thupi la valve kumagwiritsa ntchito mphamvu ya 1.5 nthawi kuposa kukakamiza kwanthawi zonse.Kuyesedwa kuyenera kuchitidwa pambuyo pa kukhazikitsa, valavu ya valve ili pafupi theka, yotchedwa test pressure test.Mpando wa valve umagwiritsa ntchito mphamvu ya 1.1 nthawi kuposa kuthamanga kwanthawi zonse.

Kuyesa Kwapadera: Malinga ndi zomwe kasitomala amafuna, titha kuchita mayeso aliwonse omwe mungafune.
